A lot of important changes to JSDT was introduced in last year (CBI, Gerrit, Gerrit Hudson review, repository join). But now this project is nearly dead.

* Old ecma support
* Old jsdoc support
* Is not extendable in many parts (model, TI, UI)
* Really slow contribution review (>= 1 year)
* Disabled validation, because not work correctly
* Many performance problems

It's strange, because JavaScript is the basis of most new web technology (MS Office plugins, nodejs and more).
